This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifirally pointed out in the appended claims.

In describing our invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corrr-zsponding parts throughoutthe several views, and in which Figure 1 is a diagrammatic view of the complete system,with parts being shown in section. v

The stortank is shown at 3 and the auxiliary tank is shown at 4, thetanks being connected to-- gether by the pipe 5 which contains the check valve 6, this valve being arranged to permit the fluid or liquid to flow from the tank 3 to the tank t, but preventing the reverse flow.

A pump 13 of the double cylinder type is associated with the tubular support-1 and its two cylinders are connected together by the manifold 14:, the handle of the pump being shown at 15. nected with the manifold and its upper end s in communicationwvith the top of a cyllnder 17, said top being preferably formed of a screw cap. A piston 18 is arranged in the cylinder and it is normally'held against the A pipe 16 has its lower end conf top orcap of the cylinder by the coil spring I.

ly and projects slightly into the auxiliary tank t. A short pipe 23 connects the bottom g j of the cylinder with the pipe 9. check valve which is arranged between the From the foregoing, itwill be seen that when the pump is actuated, air will pass from the same, through the pipe 16, into the top of'the cylinder 17. The pressure of this air will. force'the piston '18 downwardly until it uncovers the pipe 22, when the air in the cylinder will pass down the pipe 22 into I the auxiliary tank 4, thus placing the gasoline in the said auxiliary'tank under pressure so that it will be forced up the pipe 5 into the receptacle '2, the check vaive thus preventing the gasoline from being forced into the storage tank. VVhenthe gasoline reaches a level higher than the ends of the "pipes in the receptacle 2, the gasoline will begin to return to the storage tank through the pipe 9. "When enough gasoline has been forced into the receptacle 2, the pump is stopped and then the spring 19 returns the piston to its raised position and this will. place the pipe 22 in communication with the pipe 23 so that the air pressure in the am:- iliary tank is relieved by the air escaping into the cylinder from the pipe 22 and venting through the pipe 23 and the pipe 9. This will permit more gasoline to pass from the storage tank into the auxiliary tank.

In order to provide a quick return for the piston, we may place a valve 24: inthe top of i? which is by a hand. 1 A g i V lever so that by ope'ning the said valve by hand, the air will quickly escape above the piston and permit it to return quickly and thus remove pressure from the gasoline in the tank 4 and vent the said tank so that it may be refilled from the storage tank.

By opening the valve in the pipe 10,'the gasoline will flow from the receptacle 2 into the tank of the car and by opening the valve in the pipe 12, the gasoline will drain from the receptacle 2 back into the storage tank.

hen the receptacle 2 is being emptied, the pipe 9 acts as an air vent for replacing the gas in the said receptacle by' air.

It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.

Ve desire it to be understood that we may make changes in the construction and 1n the combination and arrangement of theseveral 7 parts, provided that such changes fall within the'scope of the appended claims. What we claim is v 1.. In combination with a device for dispensing gasoline and the like including a storage tank, an auxiliary tank, a dispensing receptacle and pipes connecting these parts in series in the order named, an air pump, a cylinder having-a piston therein, a spring for holding the piston at one end of the cylinder, a pipe connecting this end of the cylinder with the pump so that when the pump is actuated, the compressed air will move the piston, a pipe connected with the cylinder wall remote from saidend of the cylinder, said pipe being connected with the auxiliary tank so that when the piston is lowered by the operation of the pump, the said pipe will be uncovered and air will enter the same and pass to the auxiliary tank and force liquid therefrom into the receptacle and a vent associated with the cylinder for venting the pipe and the auxiliary tank when the piston is in raised position. v

2. In combination with a device for dispensing gasoline and the like including a V inder with the pump so that when the pump is therefrom into the receptacle, a'vent associ-' ated with the cylinder for venting the pipe and the auxiliary tank when the piston is in raised position and a hand operated vent .valve in the top of the piston.

3. A device for dispensing gasoline and the like comprising a storage tank, an auxiliary tank in communication therewith, a check valve for preventing the return of the gasoline in the auxiliary tank to the storage tank, a dispensing receptacle, a pipe connected with the auxiliary tank and extending through the receptacle to a pointadjacent the upper end thereof, a vent pipe connecting the upper part of the receptacle with the storage tank, a discharge pipe connected with the bottom of the receptacle, a cylinder, a pipeconnecting theupper part thereof with the auxiliary tank, a pipe connecting the lower end of the cylinder with the vent pipe, a hand operated pump, a pipe for leading the air therefrom into the top of the cylinder,

a piston in the cylinder, a spring for holding the same against the top of the cylinder, said piston moving downwardly, when the pump is actuated, to introduce compressed air into the cylinder, whereby the pipe leading to the auxiliary tank will be uncovered and air will pass from the cylinder into the said tank and force the gasoline thereitrom'into the receptacle and hand operated means for permit ting the air to escape from the top of the cylinder, whereby the spring will raise the piston and place the pipe leading from the auxiliary tank to the upper part of the cylinder in communication with the pipe connected With the vent pipe, thus venting the auxiliary tank into the storage tank.

In testimony whereof we aflix our signatures.
